Notes:
Scattering of SH wave by an elastic half space with a lining structure and a crack in anyposition and direction is studied with Green’s function, complex function and multi-polarcoordinate method. First, a suitable Green’s function is constructed, which is a fundamental solutionto the displacement field for the elastic space possessing circular lining structure while bearingout-of-plane harmonic line source load at arbitrary point. Then a crack in any position and directionis constructed by means of crack-division in half space. Finally the displacement field and stressfield are established in the case of coexistence of circular lining structure and crack, and theexpression of dynamic stress intensity factor (DSIF) at the tip of crack is given. According tonumerical examples, the influences of different parameters on DSIF are discussed
